01 / 02 Metodología · KPIs auditables

Caso de éxito verificable, no portfolio decorativo.

Un caso de éxito verificable en marketing digital B2B es documentación pública —cliente identificado, periodo concreto, métricas auditables— de una intervención que movió un KPI de negocio (no de vanity). En cronuts.digital solo publicamos casos con autorización del cliente, métrica conectada a su CRM o GA4 propio y delta atribuible vía server-side. Sin "cliente X". Sin proyecciones. Sin extrapolaciones.

La diferencia con un portfolio decorativo está en la metodología de medición: tracking server-side resistente a ad-blockers y consent mode, revenue tracking conectado al CRM (Holded, HubSpot, Salesforce, Pipedrive), atribución multi-touch con ventana coherente al ciclo B2B (30–90 días) y diferenciación entre lead, MQL, SQL y deal cerrado.

Los KPIs que medimos en cada caso B2B

Cohorte declarada · fuente auditable · ventana de atribución coherente al ciclo de venta.

06 dimensiones medidas

  1. Pipeline atribuido

    Importe en € de oportunidades creadas y atribuidas al canal o campaña, leído desde el CRM — no desde el formulario.

  2. CAC · Coste de adquisición

    Inversión total en marketing y ventas dividida entre clientes nuevos cerrados en el periodo, con cohorte declarada.

  3. MQL → SQL ratio

    Leads cualificados por marketing que ventas acepta como oportunidad real. Termómetro de calidad de la demanda.

  4. Time-to-deal

    Días entre primer touchpoint atribuido y firma de contrato. Refleja enfoque en cuentas correctas vs. trafficking masivo.

  5. NRR · Net Revenue Retention

    Facturación retenida y expandida en cuentas existentes a 12 meses. Separa marketing táctico de palanca de negocio sostenible.

  6. Atribución declarada

    Cada métrica con su fuente: CRM, GA4 server-side, plataforma de origen. Sin capturas de Looker sueltas.

Si tu agencia no te entrega estos KPIs cada mes con definición clara y fuente auditable, no estás midiendo casos de éxito — estás coleccionando capturas de pantalla.

02 / 02 Sectores · Resultado-clave verificado

Casos por sector con resultado clave.

Mismo método CRONUTS, distinto sector. Cada tarjeta enlaza al caso completo con metodología y métricas auditables.

06Sectores · 36 casos

Datos agregados de los casos publicados con autorización del cliente. Periodos y metodología detallados en cada ficha. Casos bajo NDA referenciados de forma anonimizada con permiso explícito.

03 / 03 FAQ · Casos de éxito B2B

Preguntas frecuentes sobre nuestros casos.

  1. ¿Cómo medís un caso de éxito en marketing digital B2B?
    Cada caso lleva tracking server-side conectado al CRM del cliente (Holded, HubSpot, Salesforce, Pipedrive). Medimos pipeline atribuido en €, CAC por cohorte, MQL→SQL ratio, time-to-deal y NRR. Las métricas son auditables por el cliente — nada de capturas de Looker sueltas.
  2. ¿Qué casos de éxito publicáis y cuáles no?
    Solo publicamos casos con autorización escrita del cliente y métricas auditables en su sistema. Aproximadamente el 60% de nuestros clientes optan por NDA total — esos casos los compartimos solo bajo acuerdo de confidencialidad en proceso comercial avanzado.
  3. ¿Cómo gestionáis los datos confidenciales del cliente?
    Firmamos NDA bilateral antes del kick-off. Los casos bajo NDA se anonimizan con permiso del cliente: sector, tamaño y delta numérico, sin nombre, ni dominio, ni rangos identificables. Cualquier mención requiere aprobación escrita.
  4. ¿Cómo verifico que los datos del caso son reales?
    Cada caso publicado incluye nombre del cliente, sector, periodo y enlace al sitio del cliente. Para procesos comerciales serios facilitamos referencia directa con el decisor, capturas anonimizadas del CRM y, si aplica, sesión de 30 min con el cliente actual.
  5. ¿Qué diferencia un caso de éxito real de un portfolio decorativo?
    Cliente identificado, periodo concreto, KPI de negocio (no de vanity), fuente del dato auditable y método de atribución declarado. Si falta uno de estos cinco elementos, no es un caso de éxito — es un anuncio de la propia agencia.
  6. ¿Cómo propongo mi empresa como próximo caso?
    Pide un diagnóstico gratuito. Si el ICP encaja (B2B 500K€–100M€), arrancamos Sprint 0 con KPIs declarados desde la kick-off. Tu caso solo se publica si tú quieres y los resultados están en tu CRM, no en una pintura nuestra.
